  Changing 'compile' to use an 'obj' target instead should
fix it. There's a bug with --dump-tests when a test
target is used in a configure check. (Note that since
this test probably shouldn't be reported in the regression
output, using compile is not correct in the first place.)

  The only thing that's affected is dump-tests.
The reason is that --dump-tests is handled prematurely,
before all the test targets have been generated.
